Not allowed. SQL Server security logins only, in the SQL Server login mode. Use the Windows login mode (it does not allow any password, and must be the current windows user). Otherwise, create the NT user as a login for security & database rights in SQL Server.

but in reality, these are rare and few. In fact, many DBAs report connectivity could not find a login matching the name provided, sql server issues with SQL Server as among the most frequently encountered errors. These errors can further be classified into two sub-categories: Login login failed for user reason: attempting to use an nt account name with sql server authentication request not reaching SQL Server. Login request reaching SQL Server and then failing. Let's look at each of these scenarios in this article. Scenario 1: Login request not reaching SQL Server http://stackoverflow.com/questions/2964097/error-18456-state-6-attempting-to-use-an-nt-account-name-with-sql-server-authe A typical error received by a client might be: Transact-SQL A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections 1 A network-related or instance-specific error occurred while establishing a connection http://logicalread.solarwinds.com/errors-sql-server-login-failures-pd01/ to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections There can be multiple reasons for this error, including these, based on work I've done with clients and queries I've responded to in user forums: Using the incorrect instance name. The SQL Service is not running. Port not open. (Note that telnet is the best test possible to detect this). The SQL Browser Service not running. (This is needed to get port of named instances. IP, PortNumber - can be specified to identify this issue.) Incorrect DNS entry and request going to different machine. (Note that ping is the best test to find name and IP address mapping). Scenario 2: Login request reaching SQL Server and then failing This second scenario results from authentication or security related errors. The error message received by the client would as shown below: Transact-SQL Login failed for user 'username'. (Microsoft SQL Server, Error: 18456) 1 Login failed for user 'username'. (Microsoft SQL Server, Error: 18456) For security

The XYZ group has around 10 users in there who are successfully able to access the SQL Server database. I recently added a new user to this group (at AD level), but this person is not able to access SQL Server error 18456 severity (through Mgmt Studio) and he's getting the error below Login failed for user. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. Error: 18456, Severity: 14, State: 11. I have already verified AD permissions are setup properly, user has restarted his machine, he is not part of any group that has DENY access and the SQL Server XYZ group has been removed and readded to the SQL Server instance in Mgmt Studio and server has been restarted. Any ideas on how to proceed further?

Can you have the new user try from another computer and see if that's the issue? Wondering if it's an AD setup issue, since your other users are working. –Jason Whitish Mar 25 '13 at 22:23 sqlblogcasts.com/blogs/simons/archive/2011/02/01/… –Aaron Bertrand♦ Mar 25 '13 at 22:26 Has the user logged off and logged on since the group assignment?
